1-1. Outline of Exercise Information Output System

FIG. 1 is a diagram illustrating an outline of an exercise information output system 1000 of the embodiment. The exercise information output system 1000 of the embodiment includes a detection device 1, an exercise information output device 2, and an exercise information server 3.

The detection device 1 detects a motion of swinging a golf club 2002 (an example of the exercise equipment) by an exerciser 2001.

FIG. 2 is a diagram showing an example of a mounted location and a direction of the detection device 1. The detection device 1 can measure acceleration generated in each axis direction of three axes and angular velocity generated around each axis of the three axes and is mounted on the golf club 2002.

In the embodiment, as shown in FIG. 2, the detection device 1 has a long axis direction of a shaft which is set as one axis among three detection axes (x axis, y axis, and z axis), for example, the y axis, and is mounted on a part of a shaft of the golf club 2002. The detection device 1 is desirably attached to a position close to a grip portion where an impact from hitting is barely transmitted and a centrifugal force is not generated at the time of the swing. The shaft is a handle portion excluding the head of the golf club 2002 and includes the grip portion.

The exerciser 2001 performs a swing operation of hitting a golf ball 2003 according to a predetermined procedure.

The exercise information output device 2 performs various calculations relating to a swing of the golf club 2002 (exercise equipment) performed by the exerciser 2001 using data which is detected by the detection device 1. The exercise information output device 2 extracts data from the exercise information server 3 and outputs the data. At least a part of various operations relating to the swing of the golf club 2002 (exercise equipment) performed by the exerciser 2001 may be performed by the exercise information server 3.

The exercise information server 3 includes a storage device 310 (which will be described later) which stores first exercise information (which will be described later) which is information relating to the past practice of the exercise (swing) performed by the exerciser 2001.

Communication between the exercise information output device 2 and the detection device 1 may be wireless or wired communication. Communication between the exercise information output device 2 and the exercise information server 3 may be wireless or wired communication.

1-2. Configuration of Exercise Information Output System

FIG. 3 is a block diagram showing a configuration example of the exercise information output system 1000 according to the embodiment.

The detection device 1 according to the embodiment includes a detection unit 110, a processing unit 120, and a communication unit 130.

The detection unit 110 may include an inertial sensor, for example. The inertial sensor is a sensor which detects physical quantity or a physical phenomenon (acceleration, an angle of inclination, an impact, vibration, rotation or the like) using inertia. As the inertial sensor, an acceleration sensor or an angular velocity sensor can be used, for example. In the embodiment, the detection unit 110 includes an acceleration sensor 111 and an angular velocity sensor 112.

The acceleration sensor 111 measures acceleration generated in each of three axis directions intersecting each other (ideally, orthogonal to each other) and outputs a digital signal (acceleration data) according to magnitude and a direction of the measured three-axis acceleration.

The angular velocity sensor 112 measures angular velocity generated around each of three axes intersecting each other (ideally, orthogonal to each other) and outputs a digital signal (angular velocity data) according to magnitude and a direction of the measured three-axis angular velocity.

The processing unit 120 receives acceleration data and angular velocity data from the acceleration sensor 111 and the angular velocity sensor 112, adds time information to the data, stores the data in a storage unit (not shown), generates packet data obtained by adding the time information to the stored measurement data (acceleration data and angular velocity data) to form a communication format, and outputs the packet data to the communication unit 130.

The acceleration sensor 111 and the angular velocity sensor 112 are ideally attached to the detection device 1 so that the three axes coincide with three axes (x axis, y axis, and z axis) in a rectangular coordinate system (sensor coordinate system) defined by the detection device 1, but there is an error of a mounted angle in practice. Therefore, the processing unit 120 performs a process of converting the acceleration data and the angular velocity data into data in an xyz coordinate system, using a correction parameter which is previously calculated according to the mounted angle error.

In addition, the processing unit 120 performs a temperature correction process of the acceleration sensor 111 and the angular velocity sensor 112. A function of temperature correction may be incorporated in the acceleration sensor 111 and the angular velocity sensor 112.

The acceleration sensor 111 and the angular velocity sensor 112 may output an analog signal, and in this case, the processing unit 120 may perform A/D conversion for an output signal of the acceleration sensor 111 and an output signal of the angular velocity sensor 112, generate the measurement data (acceleration data and angular velocity data), and generate communication packet data using these data items.

The communication unit 130 performs a process of transmitting the packet data read from the processing unit 120 to the exercise information output device 2 as exercise information which is information relating to a swing of the exercise equipment (golf club 2002) performed by the exerciser 2001, or a process of receiving a control command from the exercise information output device 2 and transmitting the control command to the processing unit 120. The processing unit 120 performs various processes according to the control commands.

The exercise information output device 2 according to the embodiment includes a processing unit 200, a communication unit 210, a communication unit 220, an operation unit 230, a ROM 240, a RAM 250, a storage medium 260, a display unit 270, and a sound output unit 280, and may be, for example, a personal computer (PC) or a mobile equipment such as a smart phone.

The communication unit 210 performs a process of receiving the packet data transmitted from the detection device 1 and transmitting the packet data to the processing unit 200 or a process of transmitting the control command from the processing unit 200 to the detection device 1.

The communication unit 220 performs a process of receiving the packet data transmitted from the exercise information server 3 and transmitting the packet data to the processing unit 200 or a process of transmitting the control command from the processing unit 200 to the exercise information server 3.

The operation unit 230 performs a process of acquiring operation data from a user and transmitting the operation data to the processing unit 200. The operation unit 230 may be, for example, a touch panel type display, a button, a key, or a microphone.

The ROM 240 stores a program for the processing unit 200 to perform various calculation processes or control processes, or various programs or data items for realizing an application function.

The RAM 250 is used as a work area of the processing unit 200 and is a storage unit which temporarily stores the program or data read out from the ROM 240, the data input from the operation unit 230, and computing results executed by the processing unit 200 according to various programs.

The storage medium 260 is a non-volatile storage unit which stores data necessary for long-term storage among data items generated by the process of the processing unit 200. The storage medium 260 may stores a program for performing various calculation processes or control processes by the processing unit 200 or various programs or data items for realizing an application function.

The display unit 270 displays the processing results of the processing unit 200 as a letter, a graph, a table, an animation, or other images. The display unit 270 may be, for example, a CRT, an LCD, a touch panel type display, or a head mounted display (HMD). The functions of the operation unit 230 and the display unit 270 may be realized by one touch panel type display.

The sound output unit 280 outputs the processing results of the processing unit 200 as a sound such as voice or buzzer. The sound output unit 280 may be, for example, a speaker or a buzzer.

The processing unit 200 performs a process of transmitting a control command to the detection device 1 and the exercise information server 3, various calculation processes for the data which is received from the detection device 1 through the communication unit 210, various calculation processes for the data which is received from the exercise information server 3 through the communication unit 220, or other various control processes, according to the program stored in the ROM 240 or the storage medium 260 and the programs received from the server through a network and stored in the RAM 250 or the storage medium 260.

Particularly, in the embodiment, the processing unit 200 functions as an index selection unit 10, an exercise information acquisition unit 20, a computing unit 30, an evaluation unit 40, and an output unit 50 by executing the program (exercise information output program). The exercise information output program may be executed as a program causing a computer to execute a procedure which is performed by at least any one of the index selection unit 10, the exercise information acquisition unit 20, the computing unit 30, the evaluation unit 40, and the output unit 50.

The index selection unit 10 selects an index relating to the swing, based on the first exercise information which is information relating to the past practice of the exercise performed by the exerciser 2001 and is acquired from the detection device 1 which detects an operation of swinging of the exercise equipment (golf club 2002) performed by the exerciser 2001 (hereinafter, may be simply referred to as “swing”). The first exercise information may include information relating to a plurality of times of swinging. The first exercise information may be, for example, stored in the RAM 250, the storage medium 260, or the storage device 310.

As the index relating to swing, a maximum value of a speed of a head in a swing period, a maximum value of a speed of a grip in a swing period, a timing of the speed of a grip using a timing of impact as a reference reaches a maximum value (grip deceleration timing), or an amount of change in a rotation angle of a shaft axis in a swing (shaft rotation) can be exemplified.

The index selection unit 10 calculates a propensity of swing performed by the exerciser 2001 (average value or standard deviation of the first exercise information) and selects an index to be paid attention to by the exerciser 2001 based on the calculated propensity of swing.

The exercise information acquisition unit 20 acquires second exercise information which is information relating to new swing performed by the exerciser 2001 from the detection device 1 which detects an operation of swinging the exercise equipment (golf club 2002) performed by the exerciser 2001. In the embodiment, the exercise information acquisition unit 20 acquires the second exercise information from the detection device 1 through the communication unit 210. The second exercise information may include information relating to a plurality of times of swinging. The second exercise information may be, for example, stored in the RAM 250, the storage medium 260, or the storage device 310.

The computing unit 30 computes the index relating to swing performed by the exerciser 2001 based on the second exercise information acquired by the exercise information acquisition unit 20. The computing unit 30 performs a computing for the index selected by the index selection unit 10.

The evaluation unit 40 evaluates the swing performed by the exerciser 2001 based on the computing results acquired by the computing unit 30. The evaluation unit 40 may evaluate the swing performed by the exerciser 2001 by comparing the computing results acquired by the computing unit 30 and the evaluation reference (target value or target range), for example.

According to the embodiment, since the index relating to swing is selected based on the first exercise information which is information relating to the past practice of the swing performed by the exerciser 2001, it is possible to select an index based on the propensity of the swing of the exerciser 2001. Since the new swing is evaluated based on the computing result regarding the index, it is possible to perform the evaluation according to the propensity of the swing of the exerciser 2001. Accordingly, it is possible to realize the exercise information output device 2 which can provide the exerciser 2001 with useful information for the improvement of the operation of swinging the exercise equipment (golf club 2002).

In the embodiment, the index selection unit 10 may set a reference of the evaluation of the evaluation unit 40 based on the first exercise information. The index selection unit 10 may, for example, set a target value to be a reference of the evaluation, according to a swing propensity or a skill level of the exerciser 2001, in a range of expecting the improvement by a practice of the exerciser 2001.

According to the embodiment, since the reference of the evaluation is set based on the first exercise information which is information relating to the past practice of the swing performed by the exerciser 2001, it is possible to set the reference of the evaluation according to the swing propensity or a skill level of the exerciser 2001, for example. Accordingly, it is possible to realize the exercise information output device 2 which can provide the exerciser 2001 with useful information for the improvement of the operation of swinging the exercise equipment (golf club 2002).

In the embodiment, the index selection unit 10 may select the index based on the first exercise information and instruction information which is information based on the instruction input by the exerciser 2001. The index selection unit 10 may acquire the instruction information from the operation unit 230.

According to the embodiment, since the index relating to the swing is selected based on the first exercise information which is information relating to the past practice of the swing performed by the exerciser 2001 and the instruction information which is information based on the instruction performed by the exerciser 2001, it is possible to select the index by combining the propensity of the swing of the exerciser 2001 and the instruction performed by the exerciser 2001. Since the new swing is evaluated based on the computing results of the index, it is possible to perform the evaluation according to combination of the propensity of the swing of the exerciser 2001 and the instruction performed by the exerciser 2001. Accordingly, it is possible to realize the exercise information output device 2 which can provide the exerciser 2001 with useful information for the improvement of the operation of swinging the exercise equipment (golf club 2002).

In the embodiment, the exercise information output device 2 may include an output unit 50 which outputs a message based on the evaluation performed by the evaluation unit 40. The message may include the computing results acquired by the computing unit 30, useful advice for practice, and an effective practice menu. The output unit 50 may output a message by displaying letters, images, or moving images on the display unit 270. The output unit 50 may output the message by outputting voice or music from the sound output unit 280. The data necessary for outputting the message may be stored in the RAM 250, the storage medium 260, or the storage device 310, for example.

According to the embodiment, it is possible to output, for example, useful advice for practice or effective practice menu as a message based on the results of the evaluation acquired by the evaluation unit 40. Accordingly, it is possible to realize the exercise information output device 2 which can provide the exerciser 2001 with useful information for the improvement of the operation of swinging the exercise equipment (golf club 2002).

According to the exercise information output program according to the embodiment, since the index relating to swing is selected based on the first exercise information which is information relating to the past practice of the swing performed by the exerciser 2001, it is possible to select an index based on the propensity of the swing of the exerciser 2001. Since the new swing is evaluated based on the computing result regarding the index, it is possible to perform the evaluation according to the propensity of the swing of the exerciser 2001. Accordingly, it is possible to realize the exercise information output program which can provide the exerciser 2001 with useful information for the improvement of the operation of swinging the exercise equipment (golf club 2002).

According to the exercise information output system 1000 according to the embodiment, since the exercise information output device 2 which can provide the exerciser 2001 with useful information for the improvement of the operation of swinging the exercise equipment (golf club 2002) is included, it is possible to realize the exercise information output system 1000 which can provide the exerciser 2001 with useful information for the improvement of the operation of swinging the exercise equipment (golf club 2002).

2. Exercise Information Output Method

FIG. 4 is a flowchart showing an outline of an exercise information output method according to the embodiment. All of the steps shown in FIG. 4 are not limited as the compulsory configuration. Hereinafter, an example of performing the exercise information output method according to the embodiment using the exercise information output system 1000 described above will be described.

The exercise information output method according to the embodiment includes an index selection step (Step S100), a swing information acquisition step (Step S102), a computing step (Step S104), and an evaluation step (Step S106). The exercise information output method according to the embodiment may further include an output step (Step S108).

In an example shown in FIG. 4, first, the index selection step (Step S100) of selecting the index relating to swing is performed based on the first exercise information which is information relating to the past practice of the exercise performed by the exerciser 2001 and is acquired from the detection device 1 which detects an operation of swing of the exercise equipment performed by the exerciser 2001. In the embodiment, the index selection unit 10 performs the process in Step S100.

In the index selection step (Step S100), the index may be selected based on the first exercise information and the instruction information which is information based on the instruction performed by the exerciser 2001.

FIG. 5 is a diagram showing a display example in an initial stage of the index selection step (Step S100). An example shown in FIG. 5 is an example displaying options of a practice menu on the display unit 270 of the exercise information output device 2. FIG. 5 displays three options of practice menus of “I want to correct irregular course of hit ball”, “I want to correct propensity of slice”, and “I want to correct propensity of hook”. The exerciser 2001 operates the operation unit 230 and inputs instruction information for selecting one from the options. In the index selection step (Step S100), an exercise item which is inferior to a target value may be selected as the index, by comparing the first exercise information and the set target value.

When the exerciser 2001 selects “I want to correct irregular course of hit ball”, for example, the index selection unit 10 may select the “amount of change in a rotation angle of a shaft axis in a swing (shaft rotation)” from the plurality of indexes, based on the first exercise information and the instruction information. The “amount of change in a rotation angle of a shaft axis in a swing (shaft rotation)” tends to be small, if it is for an advanced exerciser. When the “amount of change in a rotation angle of a shaft axis in a swing (shaft rotation)” is small, a face angle at the time of impact is easily stabilized, and therefore, it is considered that the course of a ball that has been hit has less irregularity.

In the index selection step (Step S100), the reference of the evaluation in the evaluation step (Step S106) maybe set based on the first exercise information. For example, when an average value of the “amount of change in a rotation angle of a shaft axis in a swing (shaft rotation)” of the exerciser 2001 is 100 degrees in the first exercise information, it is generally desired to have the average value thereof within 50 degrees, and therefore, the target value (reference value) as the reference of the evaluation may be set to 50 degrees based on the desired degrees. In addition, for example, when an average value of the “amount of change in a rotation angle of a shaft axis in a swing (shaft rotation)” of the exerciser 2001 is 60 degrees in the first exercise information, the target value as the reference of the evaluation may be set to 40 degrees. Exercise information of another exerciser (for example, a professional golfer or coach) may be set as a target value.

FIG. 6 is a diagram showing a display example in a final stage of the index selection step (Step S100). An example shown in FIG. 6 is an example displaying a practice index on the display unit 270 of the exercise information output device 2. This is an example in which the “amount of change in a rotation angle of a shaft axis in a swing (shaft rotation)” is selected as an index and the target value as the reference of the evaluation is set to 50 degrees.

In the example shown in FIG. 4, after performing Step S100, the swing information acquisition step (Step S102) of acquiring the second exercise information which is information relating to a new swing from the detection device 1 which detects an operation of swinging the exercise equipment (golf club 2002) performed by the exerciser 2001 is performed. In the embodiment, the exercise information acquisition unit 20 performs the process in Step S102. In the embodiment, information based on the detection results of the acceleration sensor 111 and the angular velocity sensor 112 is acquired as the second exercise information.

In the example shown in FIG. 4, after performing Step S102, the computing step (Step S104) of computing the index selected in Step S100 based on the second exercise information acquired in Step S102 is performed. In the embodiment, the computing unit 30 performs the process in Step S104. In the embodiment, since the “amount of change in a rotation angle of a shaft axis in a swing (shaft rotation)” is selected as the index in Step S100, a computing regarding the “amount of change in a rotation angle of a shaft axis in a swing (shaft rotation)” is performed in Step S104.

In the example shown in FIG. 4, after performing Step S104, the evaluation step (Step S106) of evaluating the swing performed by the exerciser 2001 based on the computing results acquired in the computing step (Step S104) is performed. In the embodiment, the evaluation unit 40 performs the process in Step S106. In the embodiment, since the “amount of change in a rotation angle of a shaft axis in a swing (shaft rotation)” is selected as the index and the target value as the reference of the evaluation is set to 50 degrees in Step S100, it is determined whether or not the “amount of change in a rotation angle of a shaft axis in a swing (shaft rotation)” computed in Step S104 has reached the target value.

According to the embodiment, since the index relating to swing is selected based on the first exercise information which is information relating to the past practice of the swing performed by the exerciser 2001, it is possible to select an index based on the propensity of the swing of the exerciser 2001. Since the new swing is evaluated based on the computing result regarding the index, it is possible to perform the evaluation according to the propensity of the swing of the exerciser 2001. Accordingly, it is possible to realize the exercise information output method which can provide the exerciser 2001 with useful information for the improvement of the operation of swinging the exercise equipment (golf club 2002).

In addition, according to the embodiment, since the reference of the evaluation is set based on the first exercise information which is information relating to the past practice of the exercise performed by the exerciser 2001 in Step S100, it is possible to set the reference of the evaluation according to a swing propensity or a skill level of the exerciser 2001, for example. Therefore, it is possible to realize the exercise information output method which can provide the exerciser 2001 with useful information for the improvement of the operation of swinging the exercise equipment (golf club 2002).

In addition, according to the embodiment, in Step S100, since the index relating to swing is selected based on the first exercise information which is information relating to the past practice of the swing performed by the exerciser 2001 and the instruction information which is information based on the instruction by the exerciser 2001, it is possible to select the index by combining the propensity of the swing of the exerciser 2001 and the instruction performed by the exerciser 2001. Since the new swing is evaluated based on the computing results of the index, it is possible to perform the evaluation according to combination of the propensity of the swing of the exerciser 2001 and the instruction performed by the exerciser 2001. Accordingly, it is possible to realize the exercise information output method which can provide the exerciser 2001 with useful information for the improvement of the operation of swinging the exercise equipment (golf club 2002).

In the example shown in FIG. 4, after performing Step S106, the output step (Step S108) of outputting a message based on the evaluation in Step S106 is performed. In the embodiment, the output unit 50 performs the process in Step S108.

FIG. 7 is a diagram showing a display example in the output step (Step S108). An example shown in FIG. 7 is an example displaying a result of evaluation on the display unit 270 of the exercise information output device 2. In the example shown in FIG. 7, the “amount of change in a rotation angle of a shaft axis in a swing (shaft rotation)” computed in Step S104 is displayed. In the example shown in FIG. 7, since the “amount of change in a rotation angle of a shaft axis in a swing (shaft rotation)” is greater than 50 degrees which is the target value, advice for improving the swing is displayed.

According to the embodiment, it is possible to output advice or effective practice menu as a message, for example, based on the result of evaluation acquired in the evaluation step (Step S106). Therefore, it is possible to realize the exercise information output method which can provide the exerciser 2001 with useful information for the improvement of the operation of swinging the exercise equipment (golf club 2002).

In each Step Shown in FIG. 4, it is possible to change the order of the steps within a range that does not disturb the embodiment.
